19 Claims.

The present invention relates generally to improvements in the art of dispensing liquids, and relates more particularly to improvements in the construction of spray heads.

Generally defined, an object of our present invention is the provision of an improved plumbing fixture which is simple in ccnstr ction, neat and attractive in appearance, and highly efilcient and practical in use.

As shown in Patent No. 2,173,064., granted September 12, 1939, to Julius El. Judell, it has heretofore been proposed to attach a spray head to the end of a normally concealed hose for use in connection with kitchen sinks or the like. The spray head therein shown, however, is not of the most practical construction since it is highly desirable to provide a spray head of highly attractive appearance and conveniently accessible so as to permit disposition in a retaining socket placed anywhere upon the sink without etracting therefrom and it is furthermore x remely desirable to provide a spray head which can safely used with either hot or cold water.

It is therefore a more specific object of our invention to provide a spray head of neat and attractive appearance and which is adapted for use in connection with kitchen sink assemblages of the aforementioned type.

A further specific object 0:"; our invention is to provide an insulated spray head which provides adequate protection to the user when hot water is passed therethrough.

A still further object of our present invention is to provide a spray head adapted to cooperate with a flexible conduit and with a and of such shape and construction as to be readily manipulated.

Still another specific object of the invention is to provide a spray head of durable construction which may be dropped or bumped against hard objects without danger of breaking the nozzle or other objects.

An additional specific object of present invention is to provide a spray which may be manufactured at moderate cost and which may be readily installed and operated.

These and other specific objects advantages will be apparent from the following detailed description.

A clear conception of the several features constituting our present improvement, and of the mode of constructing and of applying spray heads built in accordance with the invention, may be had by referring to the drawing accompanying and forming a part of this specification wherein the reference characters designate the same or similar parts in the various 'iews.

Fig. l is a fragmentary part sectional front view of a sink showing the improved spray head in normal position as applied to a kitchen sink assemblage;

Fig. 2 is a transverse vertical section through the sink taken along the line 2-2 of l showing the improved spray head in extended position;

Fig. 3 is an enlarged fragmentary part sectional side elevation of the improved spray h ad as applied to a portion of the sink; and Fig. 4 is a transverse horizontal section through the assemblage taken along the line l& of Fig. 3.

While the invention. has been shown and described as being specifically embodied in a special type of sink assemblage, it is not the intent to thereby unnecessarily restrict the scope, since the features are more generally applicable to plumbing fixtures.

Referring to the drawing, the sink assemblage shown in Figs. 1 and 2, comprises in general a sink having a basin 5 provided with a drain 5, drain boards 7, 8 for dishes or other objects formed integral with the opposite ends of the basin, a rear wall 9 formed integral with the basin and'drain boards, and an apron it also formed integral with the basin drain boards and extending therearound from one end of the rear Wall 9 to the other. The sink also has an integral elevated portion l l disposed between the basin 5 and the rear wall t, and attached to the -medial part of this elevated portion ii is swing spout faucet 52 having hot and cold control valves it, M respectively and an adjustable spout 15 disposed between these valves l3, l4. Communicating with the lower portion of the spout I5 is a flexible. hose or conduit l through which hot or cold water 'may be diverted by manipulation of a diverter valve control ll. This flexible hose it is confined beneath the sink and is concealed by the sink cabinet it.

The present improved spray head 55, shown in detail in Fig. 3, consists of a hose attachment plug or fitting 2% having a hose retaining knob 2i, a curved brass tube 22 secured at one end to the fitting Eli and having its opposite end providcd with a spray nozzle 23. A rubber covering 24 provides a convenient gripping handle above the nozzle and is either pro-molded and slipped over the tube 22 and around the spray nozzle or it may be molded directly upon. these elements', and the end of the covering 24 adjacent to the fitting 20 is embraced and protected against damage by a snug fitting sleeve 25 having a polygonal lower end. A tubular guide nut 26 having a polygonal hole is adapted to coact with the polygonal portion of the sleeve 25 to retain the spray head I9 in any desired normal or inactive position, and is secured within a bore 27 in the elevated portion I I of the sink by means of a sleeve 28 coacting therewith, see Figs. 3 and 4.

The curved tube 22 may first be formed in the desired shape and size with one end thereof threaded or otherwise adapted to receive the hose fitting 20. The spray nozzle 23 of desired shape and size may then be threaded or otherwise attached to the tube 22 at the end remote from the threading and the rubber covering 24 may thereafter be applied to the tube 22 and nozzle 23. The hose fitting 20 may then be attached to the threaded end of the tube 22 and the sleeve 25 may thereafter be attached thereto around the adjacent end of the covering 24, thus completing the spray head assemblage. A hole 21 may then be bored in any desired and conveniently accessible part of the elevated portion II of the sink, but it is preferable to have this bore 21 to the left of the faucet I2 and near the drain board 8 as shown in Fig. 1 because in washing dishes, the dirty dishes are usually placed on the drain board I, are washed in the basin 5 and are then placed on the drain board 8 for rinsing which may be con- Veniently done with the spray head and. apparatus shown. The nut 26 may then be placed within the bore 21 and the sleeve 28 may be screwed or otherwise attached thereto from the lower side of the sink portion II, thus firmly securing the nut 25 in position. The flexible hose I6 which communicates with the diverter, may then be pulled through the hole in the nut 26 and may thereafter be forced over the knob 2I of the fitting 20 until it tightly embraces the fitting.

From the foregoing description it will be apparent that the present invention provides a simple spray head which is extremely neat in appearance, durable in construction, and highly efiicient in use. The spray head may be formed in any desired shape or size and may be positioned on any desired portion of the sink without detracting therefrom. The rubber or similar covering provides a highly eflicient insulating'shield serving as a protection to the user against burning, and furthermore as a protection against possible chipping of the sink enamel and of dishes resting upon the sink. The improved spray head is moreover attractive in appearance, and by virtue of the polygonal or square formation of the sleeve 25 and of the hole in the nut 26, the nozzle or head l9 may be set in various fixed positions when not being handled. Obviously, instead of using rubber, other resilient material may be employed, and the covering 24 provides an enlarged conveniently accessible gripping portion above the nozzle and thus facilitates safe manipulation of the nozzle. The diverter valve and control I! provide simple means for by-passing the flow either to the spout I8 or to the spray head I9 at the will of the operator. The improved spray head hasproven highly successful in actual commercial use, and can be conveniently manufactured for sale at moderate cost.

It should be understood that it is not desired to limit the invention to the exact details of construction and to the precise mode of utilization herein shown and described, for various modifications within the scope of the claims may occur to persons skilled in the art.
